Provided is an electric wire straightening device capable of correcting a twist generated around an axis of an electric wire. An electric wire correcting device includes an electric wire holding part provided rotatably around an axis of the electric wire for holding an electric wire having been withdrawn from an electric wire reel so as to further withdraw the electric wire toward a side opposite to the electric wire reel and, a rotation driving part rotating the electric wire holding part in an twist backing direction opposite to a twist around an axis of the electric wire occurring in the electric wire between the electric wire reel and the electric wire holding part by further withdrawing the electric wire from the electric wire holding part.

A method for manufacturing a straight steel monofilament for the reinforcement of belt ply of a pneumatic tyre, where the arc-height of the straight steel monofilament is less than 30 mm. The steel monofilament is plastically deformed by a twisting along the axis of the steel monofilament on a double-twist apparatus. The plastic twist deformation eliminates the surface stress difference on the steel monofilament and provides a straight steel monofilament for belt ply reinforcement. This provides a simple solution with existing apparatus to manufacture straight steel monofilament suitable for tire reinforcement with high speed for mass production.

The present disclosure relates to an automatic forming machine for plant growth supports, comprising a ring rolling system with a ring rolling unit, a mold system with a mold unit, and a welding system, which are all disposed on a machine frame, wherein the ring rolling unit can roll a metal wire and make the metal wire be formed into a ring with an opening in the mold unit; the mold system is for carrying the ring and making two free ends of the ring with an opening aligned or alternately overlap with each other; the welding system welds can weld the opening of the ring carried by the mold unit, causing the ring to become a closed ring. The present disclosure has a high automatic degree and can reduce the production time and labor cost.

The present invention discloses a bending and molding mechanism, comprising a base, wherein the base is provide with a transverse sliding rail, two transverse sliding bases are disposed on the transverse sliding rail in a sliding manner, the base is provided with a transverse driving device driving the transverse sliding bases, the base is provided with a central clamping device which can clamp the wire and can rotate around a central axis of the wire between the two transverse sliding bases, the transverse sliding bases are provided with a longitudinal sliding rail, the longitudinal sliding rail is provided with a longitudinal sliding base, the transverse sliding bases are provided with a longitudinal driving device driving the longitudinal sliding base to slide, the longitudinal sliding base is provided with a bending and molding device, one side, close to the central clamping device, of the transverse sliding base at the left side is provided with a left clamping device capable of movably extending to clamp the wire, and one side, close to the central clamping device, of the transverse sliding base at the right side is provided with a right clamping device capable of movably extending to clamp the wire. The device is simple in structure, and can bend two sides of tubular products or wires from different bending angles and different bending radii.

A configuration and method for straightening a wire as the wire pays off from a bulk package. A bulk package hat is configured to be positioned over an opened bulk package containing wire bent in a helix shape. A bearing assembly is mounted inside the bulk package hat at a position where the wire exits the bulk package hat as the wire pays off from the bulk package. A wire straightening device has a plurality of rollers and only one single plane of straightening, and is configured to apply a counter bend to the wire as the wire pays off from the bulk package through the wire straightening device. The wire straightening device is operatively connected to the bearing assembly at an angle inside the bulk package hat. The bearing assembly and the single plane of straightening rotate, continually realigning with a current direction of the wire as it pays off.

A method and a device untwists and smooths a cable end of a cable formed from single lines twisted in a twisting direction, using the device. The device includes an untwisting gripper having first and second untwisting jaws; a clamping gripper upwards of the untwisting gripper in the cable run having first and second clamping plates; and a cable gripper upwards of the clamping gripper. The method includes gripping the cable using the cable gripper; introducing the cable end between the open clamping gripper plates and the open untwisting gripper jaws; closing the plates and jaws; rotating the untwisting gripper counter to the twisting direction for untwisting the cable end; opening the jaws, reducing the jaws-plates distance and closing the plates; and smoothing the cable end by enlarging the distance between cable gripper and clamping gripper when the cable is clamped and simultaneously performing oscillating rotational untwisting gripper movements.
